CY7C1009B-20VC

Memory IC Overview

The CY7C1009B-20VC is a 128K x 8 Static RAM organized as 131,072 words by 8 bits. It features a maximum access time of 20 ns and operates within a voltage range of 4.5 V to 5.5 V. The device supports commercial ambient temperature operation from 0°C to +70°C. It utilizes a parallel interface with tri-state drivers and includes automatic power-down when deselected.

Memory IC Feature Summary

• TTL-compatible inputs and outputs for direct interfacing
• Automatic power-down functionality upon deselection
• Flexible memory expansion via multiple chip enable options

Memory IC Applications

• High-speed data buffering in embedded systems
• Cache memory implementation in industrial controllers
• General-purpose static random-access memory storage

Memory IC Procurement Notes

Verify the specific speed bin (20 ns) and package type (300-mil SOJ) against current inventory requirements. Confirm that the operating temperature range aligns with the intended commercial application environment. Ensure compatibility with existing TTL logic levels if integrating into legacy designs.

Memory IC Selection Notes

Select this component for applications requiring fast asynchronous read/write cycles without complex synchronization logic. The 300-mil SOJ package offers a compact footprint suitable for space-constrained boards. Consider the low standby power characteristics if power efficiency during idle states is a priority.

Memory IC Part Context

This part belongs to the CY7C1009B family of high-performance CMOS static RAMs. It shares functional equivalence with the CY7C109B series but differs primarily in physical package dimensions. The family provides scalable memory solutions for various digital processing tasks.

Memory IC Replacement Considerations

CY7C1009B-15VC: Offers faster 15 ns access time in the same package. CY7C1009B-12VC: Provides 12 ns access time for higher speed requirements.
